Mounting

Fire hazard due to overheating because of inadequate ventilation clearances
Insufficient ventilation clearances lead to overheating with associated risk to persons as a
result of smoke and fire. This can also result in increased downtime and reduced service
lives for devices/systems.
• Always install the Power Modules vertical with the line and motor connections below.
• When mounting, maintain a 1 mm clearance between components.
• Ensure the following ventilation clearances above and below the component:
• Only install devices in this area that do not obstruct the flow of cooling air.
• Ensure that the cooling air can flow through the Power Modules unobstructed.
Note
Mounting instructions for
• You must mount the PM240-2 Push Through Power Modules on an unpainted metal
surface in order to comply with EMC requirements.
• To be able to mount PM240-2 Push Through Power Modules, the wall thickness of the
cabinet must be ≤ 3.5 mm.
